I agree with you, great idea but too expensive. I was hoping for something really inexpensive that a student (or hobbyist) could pop in a Raspberry Pi, and a laptop, take the Pi out for experimenting, etc.

I am travelling with a small $190 HP Stream (running Linux) and for this low price I have a full on computer. I am working on my new Haskell book right now and I don't miss my more powerful Linux laptop or MacBook that I left at home. The Raspberry Pi is a powerful enough device to get work done on, and a $100 laptop case for it would be a great product.
